Question

我正在使用Grails 2.0.3和webFlow 2.0.0。

我的控制器中有一个WebFlow定义工作正常但我还想添加集成测试以方便将来的维护。

每当控制器尝试向流量范围添加一些值时，我的测试中都会出现以下异常：

ERROR org.codehaus.groovy.grails.webflow.engine.builder.ClosureInvokingAction  - Exception occured invoking flow action: No such property: poInfo for class: org.springframework.webflow.core.collection.LocalAttributeMap

这是我试图测试的My WebFlow代码的一部分：

def createFlow = { 
    initialize { 
        action { 
            if (params.eventId) { 
                flow.receivingEventId = params.eventId as int 
                ReceivingEvent existingReceivingEvent = ReceivingEvent.get(flow.receivingEventId) 
                flow.receivingEvent = new ReceivingEvent(branch:existingReceivingEvent.branch) 
            } 
        } 
        on ("success").to "addPO" 
    } 

    addPO { 
        on("add") { 
            log.debug("addPO") 
            // Initialize flow objects 
            flow.poInfo = new PoInfo(params) 
            if (flow.receivingEvent == null) { 
                flow.receivingEvent = new ReceivingEvent() 
            } 

            // validate and populate poInfo object 
            boolean objectIsValid = flow.poInfo.validateAndPopulate() 
            if(!objectIsValid) { 
                if(!flow.poInfo.hasErrors()) { 
                    flash.warning = 'poInfo.poNumber.unknown' 
                } 
                return error() 
            } 
            // add poInfo object to receivingEvent for additional processing/validation 
            String errorMessage = flow.receivingEvent.addPoInfo(flow.poInfo) 

            if(null != errorMessage) { 
                flash.warning = errorMessage 
                return error() 
            } else { 
                flow.poInfo = null 
            } 
        }.to("addPO")

........

这是我的集成测试：

class ReceivingEventCreationFlowTests extends WebFlowTestCase{ 

ReceivingEventController receivingEventController = new ReceivingEventController() 

void testInitializeFlow() { 
    startFlow() 
    assertCurrentStateEquals "addPO" 
} 

void testAddPoInfoMissingPiecesPallets() { 
    println("Hola mundo") 
    startFlow() 
    assertCurrentStateEquals "addPO" 

    receivingEventController.params.poNumber = '63055024UI1063' 
    receivingEventController.params.pro = '3' 
    println "flow scope: " + getFlowScope().getClass() 
    println ("Hola again") 
    signalEvent('add') 
    assertTrue getFlowScope().poInfo.hasErrors() 
    assertCurrentStateEquals "addPO" 
} 

@Override 
public Object getFlow() { 
    receivingEventController.createFlow 
} 

String getFlowId() { "create" } 
}

有人对我在这里失踪了什么有任何想法吗？或者如果webFlow 2.0.0和grails 2.0.3存在任何已知的集成测试问题？

我遵循书中的指导原则：Grails in Action，第9.4章：测试WebFlows ......但我仍然遇到上述错误。

提前致谢，

Grails in Action是一本非常好的书，但有些陈旧。我建议你使用单元测试代替集成测试。文档几乎不存在，但您可以在grails源代码中看到一个很好的示例：

WebFlow unit test code

你可以看到带有输入，输出，子流等的webflow。（输入和输出比GIA书更新）

在示例中，Roeche使用会话范围，您可以使用流量范围。

无法为webFlow 2.0.0运行Grails集成测试
